How do you swap faces?

Here is a suggestion that may work although I have not tried it. Make a visit to your local Pharmacy like CVS, Rite Aid etc. and pick up a Eyewear Repair Kit. They generally have a small screwdriver that may work for you. probably only around $2. Just cash in some soda cans and give it a try. The kit may have a slotted screwdriver but it probably small enough to fit the Philips head screw..

Will do. Thanks for the advice, Super.
P.S.: Just remembered I had an idea once of turning my old Steam Along Clarabel into Percy's mail coach. I never really liked the look of the TOMY mail coaches, but they're quite rare anyway, so I was thinking making my own MIGHT be a better idea.
